26 Claims.

This invention relates to lasting machines, and more particularly to machines of the bed type provided with wipers for wiping the marginal portion of shoe upper materials inwardly over an insole around an end of a shoe. An object of the invention is to provide means for controlling the heel end of an insole in lasting a welt shoe of that type in which the insole has a lip or rib (hereinafter referred to as a lip) extending around its heel end as well as along other portions thereof and against which the margin of the upper is lasted by the heel wipers, in order to support the lip against the pressure of the wipers and thus render the wipers more effective to shape the upper as required in the angle between the lip and the feather of the insole without danger of distorting or damaging the lip. The invention is herein illustrated as applied to a machine of the same general character as disclosed in United States Letters Patent No. 1,018,477, granted on February 27, 1912 upon an application of Matthias Brock, but it is to be understood that it is applicable to machines variously constructed and also applicable, in some novel aspects, to the control of the toe ends of insoles as well as the heel ends.

For the purposes in view, the invention provides a holddown for engaging the insole and supporting the lip, and controlling means so constructed that the holddown may be readily applied to the insole in proper relation to the lip with but little care or effort on the part of the operator. As illustrated, the holddown is mounted for swinging movement lengthwise of the shoe from an idle position to a predetermined position opposite the bottom of the shoe such that it will readily clear the lip when applied to the insole, and is thereafter movable heightwise of the shoe into insole-engaging position with a component of movement lengthwise of the shoe toward the lip. In the construction shown such component of movement of the holddown lengthwise of the shoe results from the cooperative action of a stop which limits the above-mentioned swinging movement thereof and an inclined face on the holddown engaged by this stop, a reverse swinging movement of the holddown toward the lip being thus effected. To seat the holddown thereafter firmly upon the insole and against the lip, the invention further provides an operating member, herein shown as a hand lever, and means for pressing the holddown upon the insole heightwise of the shoe and for also forcing it toward the lip by the movement of this member. By means of a pawl-and-ratchet device the holddown is then looked in operative position.

In machines of the illustrated type the heellasting means is supported on a carriage which prior to the lasting operation is moved by the operator in a direction lengthwise of the shoe into position for the lasting means to operate on the shoe and is then looked against retractive movement. In the construction shown the holddown and the means for controlling it are supported on this carriage to move therewith. Means provided, moreover, for unlocking the carriage after the lasting operation serves also to unlock the holddown to permit its return to starting position. Further novel features of the invention are to be recognized in this organization.

The above and other features of the invention, including various novel details of construction and combinations of parts, will now be more particularly described with reference to the accompanying drawings and thereafter pointed out in the claims.

In the drawings,

Fig. 3 shows a portion of the structure in elevation as viewed from the right with reference to Fig. 1, with parts in section;

In view of the disclosure of the general organization of machines of the illustrated type in the above-mentioned and other prior United States Letters Patent, the drawings show only a portion of such a machine, and only such parts are hereinafter referred to as it is necessary to mention for an understanding of the invention. Supported on the frame 2 of the machine for horizontal adjustment about a pin 4 is a yoke 6, and movable in directions lengthwise of the shoe along this yoke is a heel head carriage 8. Adjustably supported on this carriage is a heel wiper head i2 having thereon heel-embracing wipers M which are advanced and closed by a hand lever l6 to wipe the marginal portion of the heel end of the upper materials inwardly over the insole. Alsosupported on the head I2 is a heel band is which is closed about the heel end of the shoe by automatically acting power means (not shown). The heel head carriage 8 occupies initially an idle position farther to the right than shown in Fig. 1, and it is moved by hand toward the left to carry the Wipers into position to operate on the shoe. It is then held against retractive movement by a latch 28 pivoted thereon and engaging a plate 22 on the yoke 5. Mounted on this carriage for movements in directions lengthwise of the shoe is a shoe support or jack 24 provided with a spindle 25 for engaging the last in the usual spindle hole. A horizontal portion of the jack is provided with rack teeth 28 engaged by a pinion 30 fast on a shaft 32 mounted in bearings in the carriage 8 and having a hand wheel 34 thereon for turning it. By this hand wheel the operator moves the jack toward the right to force the heel end of the shoe against the heel band l8 after moving the carriage 8 to the position determined by the latch 20. The jack is held against retractive movement by a pivoted spring-controlled latch 36 in engagement with one of a series of teeth (not shown) on the hand wheel 34. The latch 36 is pivotally connected to the lower end of a substantially vertical lever 38 fulcrumed between its ends on the carriage 8, and the upper arm of this lever is controlled by a substantially horizontal lever 48 pivotally supported at its right-hand end on the carriage. When the lever 40 is swung upwardly it acts on a lug 42 (Fig. 2) on the lever 38 to swing this lever in the direction to cause the latch 36 to release the hand wheel 34 and thus permit return movement of the jack toward the left by a spring (not shown). Such upward movement of the lever 40 is effected by upward movement of the latch 25, on which the left-hand end of the lever 40 rests, when this latch is lifted to release the carriage 8. The lifting of the latch 20 results from upward movement of a power-operated member M on the yoke 6 after the lasting operation. Except for changes in certain parts, including the lever 40, to accommodate new structure provided by the present invention, the construction thus far described is substantially the same as heretofore, as disclosed, in part, in the previously mentioned Letters Patent and more fully, in some respects, in Letters Patent No. 1,404,188, granted on J anuary 24, 1922 upon an application of Matthias Brock.

For purposes of the present invention the carriage 8 has fast on the front thereof a bracket 45 provided with a vertical bore 48 in which is mounted a hollow plunger 5!! having fast on its upper end a holddown arm 52. A rod 54 extending from front to rear of the carriage 8 and held fast on the carriage has its front end portion threaded in the bracket 45, and the bracket is additionally secured to the carriage by a bolt 58 on which the previously mentioned latch 25 is mounted. The holddown arm 52 is so formed as to extend upwardly and rearwardly to a position over the shoe bottom where a portion thereof extends lengthwise of the shoe and downwardly toward the heel end of the insole. On its end it carries a holddown plate 58 detachably supported by means hereinafter described and arranged to hold the heel end of the insole pressed down upon the bottom of the last and to serve also as a support for the heel-end portion of the lip a, of the insole against the inwardly directed pressure of the wipers It. In the construction shown the plate 58 is circular in form and supports the lip in locations opposite the most sharply curved portions of the edge of the shoe bottom where the greatest pressure of the wipe-rs is required to shape the gathered margin of the upper properly, but it will be understood that the plate may be differently shaped to support the lip farther along the side edges of the insole if desired. It is contemplated that the same plate will be used on shoes of several sizes, but that different plates will be provided for wide variations in size.

The plunger 50 is movable upwardly and downwardly in the bore 48 of the bracket 46 which serves as a holder therefor, and insuch movements it is controlled by a pin 69 threaded in the bracket and extending into a slot 62 in the plunger. This slot is so formed that in the upward movement of the plunger the holddown arm 52 is svrung away from over the shoe bottom to the idle position indicated by broken lines in Fig. 2, and in the downward movement of the plunger the arm is swung lengthwise of the shoe to carry the plate 58 to a position over the heel end of the insole. A spring 64 tends to raise the plunger 55 and holds it normally at the limit of its upward movement determined by the pin 60 and the slot 52. In applying the plate 58 to the shoe the operator depresses the arm 52 and the plunger against the resistance of the spring 54 with one hand, while assisting in the swinging of the arm in the path determined by the pin and the slot. This swinging movement of the arm is limited by a screw 66 which is threaded in the bracket 46 and the head of which is arranged to engage a face 68 (Fig. 3) on the hub of the arm. The screw 66 is so adjusted that when it thus stops the swinging of the arm 52 the plate 58 is positioned a little farther from the extreme heel end of the shoe than the corresponding portion of the insole lip, the plate being spaced also a short distance above the insole. This insures that the plate will clear the lip as it is thereafter applied to the insole by further downward movement of the arm, regardless of such small variations as there may be in the positions of the heel ends of difierent shoes. As the operator further depresses the arm 52 to cause the plate 58 to engage the insole, the arm is swung reverse-1y, to carry the plate to the right (Fig. 2) toward the portion of the lip which it is to support, by the engagement of the head of the screw 66 with the face 58 which is inclined for that purpose as shown in Fig. 3. Such reverse swinging movement of the arm is permitted by the fact that the upper portion of the slot 52 (Fig. 4) which is Vertical and in which the pin 62 is positioned at that time, is wider than the pin.

For better accommodation to the position of the lip of the insole the plate 53 is so supported as to permit it to move relatively to the arm 52 in directions widthwise of the shoe. For this purpose there is mounted on the lower face of the end portion of the arm a resilient plate '59 which may swing in directions widthwise of the shoe about the shank of a screw 72 threaded in the arm. Another screw 4 in the arm extends through a slot 76 in the plate '59 to limit swinging movement of the plate. In one end of the plate 10 is a slot '58 to receive the shank of a screw threaded in the holddown plate 53, the head of this screw lying in a recess 82 elongated laterally of the shoe in the arm 52. The arm bears on the head of the screw 85 to press the plate 58 down on the insole while permitting the plate to tip to adjust itself to the insole. As the operator applies the plate 58 to the shoe he may swing it with its supporting plate H3 in one direction or the other to position it in proper relation to the lip of the insole laterally of the shoe. To permit detachment of the plate 58 if it is desired to use one of a different size, the plate 70 may be sprung downwardly with the head of the screw 56.

until the head of the screw 80 is clear of the recess 82. The plate 58 may then be detached by sliding the screw 80 out of the slot 78.

After the plate 58 has been applied to the insole in the manner above described, it is pressed more firmly down on the insole and is also forced firmly against the lip lengthwise of the shoe by use of a hand lever 84. This lever is mounted on a sleeve 86 on the rod 54 and carries a roll 88 arranged to engage an inclined face 99 on the hub of the arm 52. A spring 92 connected to an arm 94 depending from the hub of the lever 84 tends to swing the lever upwardly and holds it initially in the position determined by engagement of the arm 94 with 2. lug 96 on the bracket iii. When the operator depresses the lever 84 the roll 88 by its action on the inclined face 96 tends not only to force the arm 52 and the plunger o farther downwardly, but also to swing the arm toward the right (Fig. 2) to force the plate 58 firmly against the lip of the insole. It will be evident that either such movement of the arm may take place independently of the other. To retain the plate in operative position there is provided a pawl 98 arranged to engage ratchet teeth lllfl formed on a member I02 fastened on the arm 9d. The pawl is mounted on a rod 904 on the bracket 46 and is held against the teeth me by a spring 36 connected to the arm 94. Rigidly connected to the pawl is an upwardly extending arm M8 the end of which is curved toward the right and overlies an inclined face NE on the lever 49. When this lever, therefore, is raised by the latch 28 to release the hand wheel 34 as previously described, it acts also to swing the pawl es away from the ratchet teeth sec and thus to release the lever 84 and the holddown to permit the holddown to be returned to its initial position by the spring es. It will be understood that the spring first raises the arm 52 until the plate 58 is clear of the lip of the insole, after which the arm is further raised and is swung to the right in the path determined by the pin es and the slot 52.

The manner of operation of the parts described may be briefly summarized as followsz The operator moves the carriage 8 toward the left to the position in which it is held by the latch 29, and after mounting a shoe on the jack turns the hand wheel 34 to move the jack toward the right and thus to force the shoe against the heel band 55, the jack being held against retractive movement by the latch 36 in engagement with the hand wheel. By the operation of power means the heel band is then closed about the heel end of the shoe. Machines of the illus trated type are provided with toe-lasting means, and the operator may proceed to last the toe end of the shoe before lasting the heel end, if desired. Before lasting the heel end the operator, with one hand, depresses and swings the arm 52 in the path determined by the pin 5!! and the slot 62 until the swinging of the arm is stopped by engagement of its inclined face 63 With the arm in that position the holddown plate 53 is spaced a short distance above the heel end of the insole and a little to the left of that portion of the insole lip which is nearest the extreme end of the shoe. The operator then further depresses the arm 52 to move the plate 58 into engagement with the insole, and in response to this movement the arm is swung reversely by the action of the screw 66 on the inclined face 68 to carry the plate 58 toward the portion of the lip which it is to support. Having thus placed the holddown plate upon the insole, the operator depresses the lever 84, and in this operation the roll 88 on the lever tends by engagement with the inclined face all on the arm both to depress and to swing the arm, thus forcing the plate 58 more firmly down upon the insole and also forcing it firmly against the lip of the insole. The pawl 98 then acts through the lever 84 to hold the arm and the plate securely in operative position. The operator thereafter advances and closes the wipers i i to wipe the marginal portion of the upper materials inwardly over the insole and against the lip, the holddown plate providing a firm support for the lip so that the upper may be wiped inward with as much pressure as desired without danger of distorting or damaging the lip. If cement is used to secure the heel end of the upper materials in lasted position, such cement will have been applied to the materials before the operation of the wipers. After the upper has been lasted satisfactorily the operator withdraws the wipers, and thereafter the power means, which controls the member 44,

is actuated to cause the lifting of the latch 20 and the lever iii! to release the carriage ii and the jack 2Q. Simultaneously the'lever 40 operates the pawl 98 to release the lever 84 and the holddown, the latter being then returned to its starting position by the spring 64.
